## Summary description

Polished Black Pebble IV stones by Terra Natura, sized 20–30 mm, supplied in a 10 kg pack for use as aquarium and terrarium substrate or decoration. These gravel stones provide a smooth, uniform decorative layer for tanks, paludariums and reptile enclosures, suitable for creating natural-looking floors, hiding spots and stable plant or ornament placement.

## Long description

Polished Black Pebble IV stones by Terra Natura are smooth decorative gravel sized 20–30 mm, supplied in a 10 kg pack for aquarium and terrarium use. These rounded pebbles form a uniform layer that enhances the visual appearance of freshwater tanks, paludariums and reptile enclosures while providing stable support for ornaments and plants. The polished surface reduces sharp edges and creates a natural, low-profile substrate suitable for decorative layouts and hiding spots.
Advantages
These polished black pebbles offer consistent size and shape, which simplifies tank layout and creates an even appearance. The smooth finish minimizes abrasion to fish, invertebrates and reptile feet, and the dark color highlights plants, corals and ornaments. Supplied in a 10 kg package, the product is convenient for covering medium to large surfaces and for creating layered designs. The inert nature of decorative gravel makes it compatible with most aquarium water parameters and terrarium substrates.
Suitable for
Aquarium substrate for freshwater tanks and paludariums
Terrarium flooring for reptiles, amphibians and invertebrates
Decorative layers for plant arrangements and ornaments
Creating hiding spots and stable bases for décor
Key specifications
Pebble size: 20–30 mm
Finish: polished, smooth surface
Color: black
Package weight: 10 kg
Application: aquarium and terrarium decorative gravel
How to use
Rinse the pebbles thoroughly with clean water before placing them in an aquarium or terrarium to remove dust and fines. Spread an even layer across the base of the tank to the desired depth, taking care to leave sufficient depth for plants or burrowing species if required. For aquariums, combine with appropriate filtration and biological substrate layers as needed; for terrariums, arrange rocks and hideouts on the gravel to create stable structures. Regular vacuuming or siphoning of surface debris will maintain cleanliness and visual appeal.
Usage recommendations
Rinse before use and monitor water parameters after installation in aquaria. Avoid mixing with chemically reactive substrates; when used with live plants, ensure appropriate nutrient layers or root tabs are included.
